There's nothing in the DNS protocol to tell one DNS server to become a
slave of another for a particular zone. DNS server configuration is
*independent* of the protocol. The operator has to tell a DNS server
which zones to serve, and whether they are master zones or slave zones.

Some DNS servers, such as PowerDNS have features to allow a master to
configure slaves automatically, but this is not a standard feature, and
NSD certainly does not have this feature.

Anand
